这次给大家带来怎样使用Vue结合Video.js播放m3u8视频,使用Vue结合Video.js播放m3u8视频的注意事项有哪些,下面就是实战案例,一起来看一下。

首先,我们需要在vue工程中安装video.js相关依赖。

npm install --save video.js npm install --save videojs-contrib-hls

然后,我们需要引入videojs的css文件,例如在main.js中引入

import 'video.js/dist/video-js.css'

接着,我们在需要播放视频的页面引入js对象

import videojs from 'video.js' import 'videojs-contrib-hls'

指定一个video容器,例如:

<video id="my-video" class="video-js vjs-default-skin" controls preload="auto" poster="../assets/video.png"> <source src=":7086/aaa/213/stream/1.m3u8" type="application/x-mpegURL"> </video>

最后,我们在mounted节点初始化播放器:

videojs('my-video', { bigPlayButton: false, textTrackDisplay: false, posterImage: true, errorDisplay: false, controlBar: true }, function () { this.play() })

Video.js中m3u8视频清晰度切换
